v To all whom it may concern:

Be it known that I, JOSEPH GEORGE HUo'r,

a subject of the' King of Great Britain, residing at Montreal, Province of Quebec,

Canada, have invented certain new and useful Improvements in Casement-Window Adjusters f'and I do hereby declare that. the

following is a full, clear,an'd exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

The invention relates to improved means for adjusting and controlling casement win dows, doors and the like and the object of the invention is to provide means for automatically retaining the window sash or door to which the adjuster is connected at any desired open position or when the same is in its closed position. 1

A further object of the invention is to provide a simple, durable and eflicient device of this character which may be readily installed or removed and one which will be comparatively inexpensive to manufacture therebyrendering the same commercially desirable.

With the above and other objects in view theinvention consists of the novel features of construction. crmmination. formationand arrangement of parts aswill be hereinafter more fully described and particularly pointed out in the appended claims.

I11 the accompanying drawings there has been shown the simple and preferred forms of the invention it being evident, however, that no limitation is necessarily made to the precise structural details therein exhibited but the right is reserved to any changes, alterations, or modifications to which recourse may be had to come within the scope of the invention without departing from the spirit thereof or sacrificing the efficiency of the same.

In the drawings: 1

Figure 1 is a plan view embodying the invention showing the same when the window sash to which it is applied is opened and also showing the same in dotted lines when the window sash to which it is applied is in its closed position;

Fig. 2 is a detail section taken on the line -2-2 of Fig. 1;

Fig. 3 is a detail section;

Fig. 4 is a view similar to Fig. 1 illustratingil a slight modified form of the invention; an

Fig. 5 is a detail cross section through the" arms when closed together.

Referring now more partlcularly to the drawings wherein llke and correspondlng parts are designated by similar reference characters throughout the several views the Specification of Lettersratent. Pat nted Feb. en, mar.

numeral 1 indicates-a window casing shown I window respectively. These arms are preferably stamped from sheet metal as shown having their lower adjacent faces fiat and adapted to lie parallel to each other and extending longitudinally through the entire length of each arm is a reinforcing bead. One end of the arm 5 is pivotally connected as at 6 to a bearing bracket 7 permanently connected to the sash.

One end of the arm 4 is pivotally connected to circular block 8 which is adapted to be detachably mounted within a socket bearing plate 9. This bearing plate is fixed. to the sill of the window casing by means of the set screws 10 and has its medial por tion raised to form a socket 11. The socket 11 is provided with an opening through which may be inserted the block 8 and to retain this block within the socket 11 a lug 12 is formed integral with the periphery of the block so that it will travel beneath the flange 13 formed with the socket 11 thereby permitting the block 8 to rotate within the socket but at the same time prevent its withdrawal. When it is desired to disconnect the arm 4 from the window casing I provide within the flange 13 a notch 14 so that when the arm is turned at right angles to the sill of the window casing the h1g1). will register with the notch and by pulling outwardly on the block 8 the same may be removed from the socket. To retain the sash in its adjusted position I provide a 13110- tional connection between the connecting ends of the arms 4 and 5. From Fig. 1 it will be noted that the connecting ends of per and steel so that by two different metals rubbing against each other a frictional connection is provided. The plates l6'are preferably made of copper'and the intermediate plates 17 are preferably made of steel so that there will be layers of different contacting metals. The adjacent faces of the.

enlarged-circular ends of thearms 4 and 5 are provided with annular recesses in which "are arranged copper rings 18' and interposed between these rings is an annular viding a and. 17 0 steel strand of metal 19. The connection between the arms 4and 5 provides means for increasing friction so that the windowsash will be retained in 'its adjusted position. The rings 18v and 19 providing the frictional' connection between the ad acent faces at'the connection between the .arms 4 and 5 and the plates arranged upon the outer faces of the arms at the connection provide frictional connections between the arms and the heads of the connecting rivet 15. By proplurality of superimposed plates 16 differentmetals ,for forming the frictional connection should any one of the plates adhere to the arms 4 or ,5 or to any of the other adjacent plates the remaining plates which are free to turn upon each other will retain this frictional connection and the purpose of the connection will not be impaired. i

From the foregoing it is obvious that the adjuster will permit the radial opening and closing 0f ,a casement window sash or door to whlch it maybe applied audit will brace "the same to prevent rattling bythe wind whether opened or closed and at thersame time firmly holding-the same in any position to which it may be swung upon its hinges without any occasion for special maclear.

nipulation and permitting the door or window sash to which it is applied to open f This frictional resistance between the companion arms 4 and 5 is not enough to cause annoyance in opening and closing the windows. L

In Figs. 4 and 5 of the drawings I have illustrated a slightly modified form of the in vention wherein the adjuster may be also used as a locking device for locking the sash when it is closed. In Fig. 4 I" have shown the device applied to the sash and window casing indicated by the numerals2 and 3 re.- spectively and the adjuster is of the same construction as the one shown in Figs. 1 and -3 of the drawings, but I have added to each of the arms 4 and 5 thereof the projecting Fig. 4 of the drawings.

and resistance lugs 20 and 21 whereby the arms will be locked together as will be later described. It will also be noted that in this figureof the drawings the bearing plate 9 is connected 7 4 and 5on'the sash and window casing respectively lie one above the other or in the same'alinement and the arms assume the position as indicated in dotted lines as at A in When the arms have assumed this position the lug 21 carried by the arm 5 extends over the edge of the arm 4 and likewise the lug 20 of the arm 4 eiztends over the edge of the arm 5 as better shown in Fig. 5 of the drawings. When the window sash is closed and the arms of the adjuster are in the position as shown in dotted lines as at A the window sash may be I readily opened and the lugs 20 and 21 will permit the respective arms of the adjuster to pass but when the arms have been swung around their outer pivot connections and have assumed the position asshown at B in dotted lines of Fig. 4 of the drawings the window sash will be locked and held against opening by means of the lugs 20 and 21.

Having thus fully described my inven tion, what -I claim asnew and desire to secure by Letters Patent is:

1. A casement window adjuster comprising a pair of companion arms, means for pivotally connecting one end of said arms together'the adjacent faces of said arms having annular grooves formed therein, resistance members arranged within said grooves, plates arranged u on the outer faces of said arms around sai pivotal connection.

. 2. A casement, window adjuster comprisinga pair of companion arms, a pivoted connection between one end of said arms, an

nular lates arranged concentric with said pivoted connection and resting adjacent to the inner faces of said arms, a rin interposedbetween said plates, and a p urality of superimposed plates arranged upon the outer faces of said arms and concentric with said pivoted connection. 1

, 3. The combination with a window casing and a window sash pivotally mounted therein, an arm pivotally and detachably connected to thewindow casing adjacent its medial portion, a companion arm pivotally connected at one end to the window sash, means for'frictionally connecting the inner ends of the arms together, a lug projecting from one edge of the companion arm and adapted to engage over the other arm when the window 1,a1e,sao new,

sash is closed within the window casing, the other arm having a depending lug projecting from one edge thereof at the opposite side of said arm to Which the lug is projeoted from the companion arm and this lug is adapted to engage over the companion arm when the window sash is closed, the pivoted connections'between ,said arms and the window casing and window sash respectively adapted to lie concentric when the window sash is closed whereby when said arms are swung upon the pivoted connections to the window casing and window sash respectively so as to lie at a straight angle from their normal position when the WindoW sash is closed the arms will be locked together and the windowsash held against opening.

In witness whereof I have hereunto set my hand.

JOSEPH GEORGE HUOT.
